These movements are repeated until the desired amount of cloth is laid-up on the table.

The connecting member 35 has vertically positioned rectangular guide bars 40 secured thereto in any suitable manner, such as by pins 4 I. The guide bars 40 are spaced apart and form between them a channel 42.

A vertically elongated rectangular bar 43 is fixed to each end wall by bolts 44. Each bar 43 has an elongated slot 45 centrally thereof. The cross-sectional dimensions of the bar 43 are made to permit the connecting member 35 to be freely slidable in contacting relation therewith.

A hand knob 46, having an integrally threaded bar 4! passing through the slot 45 is in threaded engagement with the connecting member 35. By adjusting the hand knob, the connecting member 35 may be frictionally secured to the rectangular bar 43 in selected vertical positions.

By slightly unscrewing the hand knob, the connecting member 35 is released from excessive frictional restrainment. It is thus possible, by moving the laying-up rollers on one side of the carriage l I from the table 12 to cause both connecting members 35 at opposite end walls 13, i3 to move vertically and to cause the roller on the opposite side of the carriage to move equally vertically in the same direction from the table.

As shown in Figures 4 and 5, a compression spring 48 is held fixed at its upper end by an angle member 49, which is fixed to the wall I3. The lower end of the spring 48 rests on and exerts pressure on the vertically slidable connecting member 35. It will be noted that upon release of the frictional restraining means caused by slightly unthreading of the hand knob 45, that due to the downward pressure of the spring 48 on the connecting member 35, the laying-up rollers will automatically rise to an out-of operation position above the table I2.

Figures 5 and 7 show a modified form of linkage mechanism similar to that shown in Figures 3 and 4 and wherein a modified elongated member 43' extends further upwardly above the hand knob 46 than shown in Figure 3. The member 43 has a slot 45' considerably more elongated than the slot 45 shown in Figure 3.

As best shown in Figure 5, a shaft 57 passes through the slot 45'. An open-face type disc cam 50 is fixed to the shaft 51 and rests on the connecting member 35. It will be seen that when the connecting member 35 is raised or lowered, that the cam will rotate and follow the movements of the connecting member.

As best shown in Figures 6 and 7, a centrally apertured dial 5| is secured to the wall I3 by screws 52 and provides passage therethrough for the shaft 51. The dial has. graduations 53. A pointer 54 is fixed to the shaft 5! and has its free end terminating at the graduations 53. It will be noted that when the rollers 3| are moved to and from table l2, that the resultin movements of the connecting member 35 cause the cam 56 to follow the said movements and this causes the pointer 54 to rotate and indicate on the dial the number of layers of fabric layed-up on the table [2.

In accordance with the patent statutes I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention as defined by the appended.

claims.

I claim:

1. In a cloth laying-up and feeding machine, a table, a frame having upright end walls mounted on wheels and a transverse roll supporting shaft, said frame being movably mounted lengthwise of said table, two arms pivotally mounted on each of said walls, said arms being spaced apart equally from said shaft, said end walls having upright guide means, an elongated horizontally positioned connecting member slidably mounted on said guide means, and being vertically adjustable, said connecting member havin elongated slots at each end, said arms having projecting pins i jarms, whereby when the free end of one of said arms is moved to or from said table said connecting member is moved vertically and causes the free end of the other arm to move equally in the same direction relative to said table, said arms and said connecting bars serving to support said cloth in laying position and threaded means for frictionally restraining said connectin members for maintaining said laying-up bars in position.

2. In a cloth laying-up and feeding machine, a table, a frame having upright end walls mounted on wheels and a transverse roll supporting shaft, said frame being movably mounted lengthwise of said table, two arms pivotally mounted on each of said walls, said arms being spaced apart equally from said shaft, said end walls having upright guide means, an elongated horizontally positioned connecting member slidably mounted on said guide means, and being vertically adjustable, said connecting member having elongated slots at each end, said arms having projecting pins seated in said elongated slots and connecting said arms to said connecting member for movement in coacting relation, horizontally positioned bars respectively extending between said walls on opposite sides of said shaft and being connected to the lower end portions of said arms, whereby when the free end of one of said arms is moved to or from said table said connecting member is moved vertically and causes the free end of the other arm to move equally in the same direction relative to said table, said arms and said connecting bars serving to support said cloth in laying position and threaded means for frictionally restraining said connecting members for maintaining said laying-up bars in position.

3. In a cloth laying-up and feedin machine, a table, a frame having upright end walls mounted on wheels and a roll supporting shaft, said frame being movably mounted lengthwise of said table, two arms 'pivotally mounted on each of said walls, said arms bein spaced apart equally from said shaft, said end walls having upright "guide means, an elongated horizontally positioned connecting member slidably mounted on said guide means, and being vertically adjustable, said connecting member having elongated slots at each end, said arms having projecting pins seated in said elongated slots and connecting said arms to said connecting member for movement in coact ing relation, horizontally positioned bars respectively extending between said walls on opposite to said table, said arms and said connecting bars serving to support said cloth in laying position on opposite sides of said shaft and in a horizontal plane, and releasable means carried by said connecting member and in engagement with said guide means for frictionally restraining said connecting member for maintaining said laying-up bars in position.

4. In a cloth laying-up and feeding machine, a table, a frame having upright end walls mounted on wheels and a roll supporting shaft, said frame being movably mounted lengthwise of said table, two arms pivotally mounted on each of said walls, said arms being spaced apart equally from said shaft, said end walls having upright guide means, an elongated horizontally positioned connecting member slidably mounted on said guide means, and being vertically adjustable on said guide means, said connecting member having elongated slots at each end, said arms having projecting pins seated in said elongated slots and connecting said arms to said connecting member for movement in coacting relation, horizontally positioned bars respectively extending on opposite sides of said shaft and being connected to the lower end portion of said arms, whereby when the free end of one of said arms is moved to or from said table said connecting member is moved vertically and causes the free end of the other arm to move equally in the same direction relative to said table, each of said walls having a compression spring fixed at its upper end and exerting pressure on a connecting member at its lower end, said arms and said connecting bars serving to support said cloth in laying-up position on opposite sides of said shaft and in a horizontal plane, and releasable means carried by said connecting member and in engagement with said guide means for irictionally restraining said connecting member for maintaining said laying-up bars in position.

5. In a cloth laying-up machine, a table, a. frame having upright end walls mounted on wheels and a roll supporting shaft, said frame being movably mounted lengthwise of said table, two arms pivotally mounted on each of said walls,
